Surprising Findings
The researchers claimed astaxanthin reduces wrinkles in their conclusion, but their own data shows no statistically significant effect (p=0.11)
This is a classic example of 'publication bias' or 'spin' in research - the conclusion doesn't match the actual results. Readers might assume the study proves wrinkle reduction when it doesn't.
Practical Takeaways
If you want to try astaxanthin for skin health, a dose of 2-12mg daily for at least 4 weeks may help with skin hydration and elasticity
